TriNet SOI MPN believes in the benefits of a California Medical Provider Network (MPN) for providing medical treatment to their injured workers.  The providers chosen to participate in this DWC-certified program have been contracted because of their proven abilities to treat work-related injuries and to assure our injured workers can return to work in a safe and appropriate manner.
